Do Air Purifiers Really Work?

Specialists weighs in on whether purifiers can truly filter out bacteria, dust, smoke, mold, and more.

How do air purifiers work?

Air purifiers typically consist of a filter, or multiple filters, and a fan that absorbs and flows air.

As air moves through the filter, contaminants and particles are captured and the clean air is pushed back out into the living space. Typically, filters are made from paper, fiber (often fiberglass), or mesh, and need routine replacement to preserve effectiveness.

What are air cleansers supposed to filter out and do they in fact do it?

The majority of filters on the market are developed to catch particles like dust and pollen, but do not catch gases like VOCs (volatile organic compounds) or radon. That would require an adsorbent, like triggered carbon. The Environmental Defense Agency (EPA) warns that the functionality of air purifiers is restricted in terms of filtering out gases, and that you should often replace filters for optimum performance, typically about every 3 or so months.

Numerous air purifiers are proficient at filtering pollutant particles out of the air (dust, smoke, pollen, and so on), but they are not always great at getting rid of gaseous pollutants like VOCs or radon from the air that might collect from adhesives, paints, or cleansing products. Irritants that are embedded into furniture or floor covering are likewise not recorded by them.

In addition, the effectiveness of air purifiers in real-world situations most likely will not mimic those of controlled conditions in a laboratory (what those “99% effectiveness” claims are describing!). The area, setup, circulation rate, and the length of time it is operating for will all differ, as will the conditions in the space. In addition, there are other things happening in your house that may effect the efficacy like ventilation (open or closed windows), and brand-new particles are continuously emerging, so the air might not as filtered as the claims may have you think.

If you are concerned about mold, we ‘d advise buying a dehumidifier or humidifier to help maintain the suitable moisture levels in your home and stave off mold development issues. Air purifiers do not prevent mold development, so it is needed to remove the source of moisture that is enabling it to grow.

Can air cleansers filter the outdoor air that enters your home?

In some cases, non-organic air toxins like the VOCs we discussed previously can originate from outside your house. “There are all sorts of circumstances in structure fires where large doses of smoke inhalation may cause cyanide toxicity. That would largely need to be someone who was standing directly in or near the fire: Those individuals are brought to emergency spaces instantly,” Dr. Roten describes. “Normally, outdoors contamination or smoke or short-term bad air isn’t a consistent issue for onlookers.” The right kind of purifier can address any ecological air qualities in your location. Using neighboring wildfires as an example, Dr. Roten includes that a HEPA filter-equipped cleanser is your best choice: “Anything that has a real HEPA filter in it is probably adequate enough to filter out most all the big particles that would be concerning,” he says. “The majority of the smoky odor will likewise be resolved too.”

What should I search for in an air purifier?

CADR (clean-air shipment rate) score. This determines the cleansing speed of the cleanser for getting rid of smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is really excellent.

For correct effectiveness, you need a model developed to operate in the space size. Pick a design that is created for an area larger than the one you are outfitting it for if you wish to run it at a lower, quieter setting.

AHAM (Association of Home Device Manufacturers) Verified mark AHAM’s standards are design to ensure the safety, performance and efficiency of many home care home appliances, including air purifiers. The standards are created to provide a common understanding between producers and consumers to help make the purchasing process simpler. While voluntary, many respectable air purifiers have undergone this certification program, which typically offers a CADR score and size guidelines.

Real HEPA. True HEPA filters work at removing ultra fine particles (think: dust, dander, pollen, mold and other typical irritants in the home). The industry requirement for such is that the system should be able to get rid of at least 99.97% of particulates measuring 0.3 micron size in a lab setting. Keep in mind, it is very important to note that in reality settings, the actual effectiveness of these gadgets would be far less as new contaminants are continuously emerging. Keep in mind that there is no market requirement for the terms “HEPA-like” or “HEPA-type,” and are primarily used as marketing ploys to get customers to purchase the product.
